In federal court hearings this week, a watchdog legal group keeps the heat on the State Department for answers about the exposure of classified information during Hillary Clinton’s use of unsecure email to conduct official business when she was secretary of state.

A hearing is set Friday in U.S. District Court in the nation’s capital to address a request from Judicial Watch for Clinton, longtime top aide Cheryl Mills, and other current or former State Department officials to testify under oath.

Judicial Watch wants them to address how the department responded to its Freedom of Information Act lawsuit seeking information about the 2012 terrorist attacks in Benghazi, Libya.
